A plic tion filed. March 17, 1908. Serial No. 421,682.

To altwhom it may concern:

Be it known that I, HABY'EY CORY, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain-new and useful Improvements in Coke-Drawers.

of which the following is a spe'cification.' reference being had therein. to the accomv panying. drawing.

y invention refers to improvements in coke drawing apparatus for the purpose of extracting coke from the-oven, and is part-ioularly designed for use in what is known the beehive oven. It has for its objects to provide mechandevioe; may be easily' and .conveniently located in operat ve relation to the oven, and

mesa oven of a series successiyely; means by the extracting element may be ad e laterally. to explore the area of the oven' independently of its supporting earriage, "except as pivotally connected therewith; means whiereby the extracting element may be inserted and withdrawn 'from'the oven; means whereby the coke as drawn from the oven may be received anddelivered to a conveyor aind thereby carried to anysuitable point of discharge-;-n 1eans whereby the apparatus may be moved-along a track in front of the bank ofovens, and means for supplying and distributing the -power of a plurality of motors tothe different utilizing elements of the apparatus, together with the various features or details of construction, as shall be more fully hereinafter described.

Referring to thedrawings, Figure 1 is a general plan view showing the extracting and conveyling apparatus assembled, in position for operation in an oven. Fig. 2 is an enlarged plan view of the apparatus'show-' ing' various features of construction 111, de-

channel or other suitable form, with inter- The truck Ais composed of a main framevening transverse sills, and may if desired beprovided with an upper floor plate 7 for sup orting the extractor carriage tracks 8, i

8. Theses tracks may however, be laid directly'upon the transverse cross sills or in to a-radius developed from the pivotal cen-.

ter G around which" swin s, the carriageB. ,intracks 8, as shall be herelnafter more fully described. The extractor carriage B coinprises a structure of any suitable or convenient form, so "arranged that it may be moved laterally to the tighter the left upon flanged supporting wheels-9 running on tracks 8 and as controlled by thepivotal center C, so that it will in its movement to one side or the other always conform to' said center. i For the purpose of providing such pivoting center in a substantial manner, and with a suflicient degreeof flexibility to permit of, upward or downward variation of the extractor carriage and extractor as effected'by variations in the levels of the oven.

floors or forany other reasons, I provide an upwardly and outwardlyextending bracket composed of over-arching arms 10, 10, bolt ed or otherwise secured to the side of the truck A on the working side, which arms converge toward the pivoting terminal 11 and which thus provide ample space underneath for clearance of the extractor beam and its carriage in extreme positions, as indicated in dotted lines in Fig. I. I The extractor carriage B, whlch lsmounted'xfor-lateral travel on'tracks 8 at the top of'the main truck A, is provided. with a similar upwardly and outwardly extending arm 12 having upper and lower terminals 13 and 14, between which and pivoting termimile 11 are mounted cushioning springs 15,

'16, surrounding the pivotal bolt 17 which passes through the several termina'lsfas clearly shown. By this construction, the ex-'.

76 any other suitable manner, and are curved tractor carriage B ispivotally mounted at I a point outwardly beyond the main machine and sufiiciently close to the front of the oven for operation (see Fig. 1)" s 'o that without rigidity, having the supporting rollers or wheels'9 referred to at each side of its center, properly spaced to insure stability, and when so mounted and pivotally connected with the supporting framework 10, may be located at any position and will be firmly braced against either pushing or pulling strains.

For the purpose of shifting the extractor carriage B, I provide a spool or sheave 18..

rotatably mounted by its shaft in suitable bearings, upon which sheave are wound the inner terminals of cables 19, 19, secured at their other extremities-to fixed anchoring bolts or other holding fixtures 20, 20, of the main truck A.

in one direction or the other it will cause the shifting of the extractor carriage B correspondingly, while the cable 19 at each side will be taken up and paid out at an equal rate and will operate to positively hold the extractor carriage in any desired position when stationary.

F or the purpose of supplying winding motion to sheave 18 I employ a separate motor 21 mounted on extractor carriage B and geared with the shaft of the sheave by' gearing 22, the desired degree of speed rotation being readily secured by proper proportioning of the gears. 4

L3 is the extractor consisting of a beam having a terminal extracting element 24 of any suitable design or construction, that shown in the drawings being of wedge form for underworking, although any other designmay be utilized. The beam of the extractor is provided with a longitudinal rack 25 into which meshes the driving pinion 26 of shaft 27 mounted in suitable bearings and having a gear wheel 28 driven by the pinion Q9 of an independent motor 30 mounted upon and traveling with the extractor carriage T5, or the power of the motor may be transmitted through other suitable gearmg. The. extractor 23 1s maintained in al1nement by means of suitable guide rollers 31 and 32 located above and below and at each side of the extractor beam and at the front and back of the extractor carriage respectively as shown, or in any other suitable manner whereby to maintain the extractor beam in operative position at all times;

For the purpose of receiving the coke as drawn from the oven door and for delivering it into the continuously traveling eonveyer D. I have provided .a reciproc: .ig pan 33 of suilieient length to extend be -md \Vhen sheave 18 is rotated the oven door at each side and to always re-' ceive the coke as drawn, said pan being slidingly mounted on rollers 34- on tracks 35 ex tending parallel with the inner side frame of the machine and mounted upon bracket arms 36, or in any other suitable manner.

37 is a stationary abutment supported by a bracing frame 38 and extending downwardly into and across the interior cavity of pan 33, so that as the pan, when full of coke, is drawn backwardly, said abutment will oppose the back travel of the coke, arresting it and causing the coke at the front end of the pan, to be discharged onto conveyer D or upon an inclined apron 39 leading thereto.

Reciprocation of pan 33 is imparted in any suitable manner as by means of lever arms lt) and connecting links 40' from shaft 4L1 which is adapted to be given an intermittent movement by lever 42 and eccentric or cam 4-3 on shaft Conveyer D in turn is designed to be continuously operated during operation of the reciprocating pan 33 and is preferably driven at its lower end by means of shaft. 45 driven through sprocket gearing 40 from shaft section 4.7.

111 use the apparatus is designed to be shifted along in front of the ovens upon directions, it is provided with any suitable clutch mechanism 43 adapted to be shifted in one direction or the other by lever lilso as to utilize the power imparted through sprocket or other gearing or 51. 1 It will be understood that said separate gearings rotate in opposite directions, power being imparted to them from shaft 52 through suitable reversing. mechanism as gears 53, or directly. If desired, both axles may be driven simultaneously by means of connectg'sprocket mechanism, as indicated in I 1g.8.

1n the construction shown in thc drawings l have provided a single motor Til for the several functions of reciprocating pan 2Z3, actuating conveyor D, and for driving the supporting axle to more the carriage. Power is imparted from said motor through suitable reducing gearing 55 to shaft .56 from which shaft power is taken through gearing and clutch mechanism to recip rocate the pan, drive the conveyer, and impart traveling movementto the carriage.

It is designed that the pan and conveyor shall remain stationary during travel of the carriage. \vhenlhe power of the motor is utilized for such travel, and that when the lra\'el-ilm )arting gearing is thrown out, the pan and conveyer may be thrown in. The clutch mechanism already described whereby power is taken from shaft 52 to drive axle or axles 2 and 3. utilizes the power of shaft it through bevel gearing 5T, \\'l1ilc fol'lllt' shaft 56 being similarly provided with clutch purpose of reciprocating rock shaft 41 by eccentric 43 ot-shaft 44, said shaft is geared.

.witli shaft 56 by similar bevel gearing.

It is designed that the pan-reciprocating mechanism shall be thrown into and out of gear simultaneously with the starting and stopping of shaft section 47, for which purpose shaft 47 is arranged to be coupled to or uncoupled from shaft 56 by clutch mechan;

ism 59, the driving bevel of gearing 58 on mechanism 60. Simultaneous coupling or uncoupling of said clutches 59 and 60 will therefore impart simultaneous motion to the pan and conveyor, and for the purpose of coupling or uncoupling both of said clutch mechanisms 59 and 60 together, they are actuated by a common shift ng bar til-engaging the movable element of each movable clutch, splined on the shaft, and operated through lever mechanism 62 andGS'by the operator,

as will be readily understood. As thus constructed it will be seenthat the power may be taken from the motor for the several purposesat the proper time, the motor running continuously, or that all of the operationsmay be stopped by merely stopping the .motor.

For the purpose of supporting the conmg engineer. As thus constructed the'appa- *ratus is comprised ,withfiin a single traveling self-contained structure, adapted to receive power for the several motors through any convement trolley mechanism. it being under.- stood that the machine is provided with the customary controllers located at any suitable 1)OH1UO11 and lsthere'by under the control of v the operatorgat all tunes.

The advantage of pivoting the laterally traveling ext actor arriage in the manner described is that the .10 ation of the pivoting center closely ad acent the oven door enables the operator to locate the carriage at any desired angleyvitlnn its range of movement.

which is suflicient to explore the entire oven without intermediate shifting of the carriage.

The spring mounting of the-pivotal connection gives snthcient resiliency to the apparatus to provide for vertical movement where necessary: the mounting of the extractor car;

riage on the arc-sh a pod tracks described from the pivotal center and engagement with said tracks of the flanged supporting wheels. combined with the pivotal mounting, strongly braces the extractor carriage at all positions;

the mounting of the .motor for shifting the extractor carriage on the carriage itselt' locates it at aposition where it is readily acce'ssibl e for repair. etc.; the reciprocating pan for receiving'the coke and delivering it to the conveyer. being of easy; slow movement, avoids the crushing or grinding of the coke and delivers it to the conveyer without appreciable'tall; while the conveyer itse'lt may-be of the slat construction shown.

mounted on flexible chains.'o1' may be of any other convenient form. as for instancctiexible belting. tor the purpose of preventing breakage of the coke.

The driving of the several mechanisms either by their separate motors or by the utilization of power from a single motor is provided tor in a simple. etlicient and convenient manner. and the entire structure will be found to give satisfactory results, as toetliciency. economy of timeand labor. and with a minimum b akage.

It will be understootfl that theinvention may be changed or varied by the skilled mechanic 'in various details. or otherwise modified in structure or design. but all such changes are to be considered as within the scope of the following claims.
